Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 330,420,035, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 330,420,035 | |
| -1 | -330,420,035 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 330,420,035.
Example:
1 x 330,420,035 = 330,420,035
and
-1 x -330,420,035 = 330,420,035
Notice both answers equal 330,420,035
With that explanation out of the way, let's continue. Next, we take the number 330,420,035 and divide it by 2:
330,420,035 ÷ 2 = 165,210,017.5
If the quotient is a whole number, then 2 and 165,210,017.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 330,420,035 | |
| -1 | -330,420,035 |
Now, we try dividing 330,420,035 by 3:
330,420,035 ÷ 3 = 110,140,011.6667
If the quotient is a whole number, then 3 and 110,140,011.6667 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 330,420,035 | |
| -1 | -330,420,035 |
Let's try dividing by 4:
330,420,035 ÷ 4 = 82,605,008.75
If the quotient is a whole number, then 4 and 82,605,008.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 330,420,035 | |
| -1 | 330,420,035 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 1,031 | 5,155 | 5,827 | 11,341 | 29,135 | 56,705 | 64,097 | 320,485 | 6,007,637 | 30,038,185 | 66,084,007 | 330,420,035 |
| -1 | -5 | -11 | -55 | -1,031 | -5,155 | -5,827 | -11,341 | -29,135 | -56,705 | -64,097 | -320,485 | -6,007,637 | -30,038,185 | -66,084,007 | -330,420,035 |
